8.5.5.3 If WebLogic Node Manager Fails to Start

If WebLogic Node Manager fails to start, ensure that you copied the following domains file from IDMHOST1 to IDMHOST2: WL_HOME commonnodemanagernodemanager.domains 8.5.5.4 Configuration Changes Do Not Automatically Propagate to All Oracle Directory Integration Platform Instances in a Highly Available Topology When you change the configuration of an Oracle Directory Integration Platform instance in a high availability topology, the configuration change does not propagate automatically to all the Oracle Directory Integration Platform instances in the topology. Instead, use the manageDIPServerConfig tool to make the same configuration change for each Oracle Directory Integration Platform instance in the topology, which will ensure the same configuration across all the Oracle Directory Integration Platform instances in the topology. See Oracle Fusion Middleware Administrators Guide for Oracle Directory Integration Platform for more information about the manageDIPServerConfig tool.

8.6.1 Oracle Directory Services Manager Component Architecture

Oracle Directory Services Manager is a unified graphical user interface GUI for managing instances of Oracle Internet Directory and Oracle Virtual Directory. It is a replacement for Oracle Directory Manager, which is now deprecated. Oracle Directory Services Manager enables you to configure the structure of the directory, define objects in the directory, add and configure users, groups, and other entries. Oracle Directory Services Manager is the interface used by end users to manage their directory entries, schemas, security, and other features. Figure 8–8 shows the Oracle Directory Services Manager architecture.
